Researched profile. The figures here are modelled by us from public information, published with the sources they were drawn from. How we research.
Read Sep 2026. Figures here are a reading taken then, not a live feed.
Amazon US, through Amazon’s warehouses, is the whole of what can be measured. Their own site exists and could not be read.
Every top listing ships from Amazon, sold by Doctor Jupiter_USA with the buy box all of the time, and Amazon sells none of them itself. The seller has an account on Amazon Canada with no ratings; the kits are listed on Amazon UK, but not by this seller. doctorjupiter.com answers with a bot check, so whether it sells anything is not known. What follows is presence rather than share, and a method nobody looked for is listed as unchecked rather than counted as absent.
